This application is a continuation-in-part of U.S. application Ser. No.11/881,551, filed Jul. 27, 2007.

FIELD OF THE INVENTION

The present invention relates to a personal-care article that provides apersonal-care product that comprises at least two compositions eachhaving a concentration of hydrophobic benefit material which isnoticeably distinct from each other.

BACKGROUND OF THE INVENTION

Personal-care compositions are well known and widely used for cleansingand moisturizing skin and hair, delivering actives, hidingimperfections, to reducing the oiliness/shine, as well as, providingscent to the shower and/or the skin. The efficacy of these types ofcompositions is directly related to their frequency of use and level ofactive ingredients. In some cases, a high level of benefit agent in apersonal-care composition will maintain a benefit to a consumer forseveral days after a single application. In this case, a full bottle ofthe composition with a high level of benefit agent is not needed becausethe continued application of personal-care composition with high levelof benefit agent would not provide additional benefit to the consumerover one or two single applications. Numerous cosmetic applicationsrequire that the corresponding compositions be used at variable dose ofactive ingredients in the course of time. Up until now, it order tocarry out these treatments, the available resources have consistedeither of successive applications of increasing or decreasing activeingredient percentages in separate containers or multiplying theapplications of compositions with identical active ingredientspercentages in order to obtain the correct does for the necessarytreatment. If a treatment regime contains too many steps or too manycontainers, consumers often habituate or tire of the regime ofpersonal-care compositions over time. When this habituation occursconsumers often decrease or even or stop use of one personal-careproduct despite the benefits gained by the compliant use of the regimeof personal-care products over time. With the space in the shower orbath being limited, a typical shower or bath does not have enough space,to place multiple containers of personal-care compositions so that aconsumer can easily switch the use of one personal-care composition toanother personal-care composition with a different level of benefitagent.

SUMMARY OF THE INVENTION

The present invention relates to a personal-care article for providingat least two personal-care compositions. The personal-care articlecomprises a package and a personal-care product. The package comprisesat least one chamber, a dispensing orifice, a first zone proximate tothe dispensing orifice and a second zone distal to the dispensingorifice. The first and second zones are both located in at least onechamber. The personal-care product comprises a first personal-carecomposition substantially disposed within the first zone and the secondpersonal-care composition substantially disposed within the second zone.The first personal-care composition comprises a first concentration ofhydrophobic benefit material. The second personal-care compositioncomprises a second concentration of hydrophobic benefit material. Thefirst concentration of hydrophobic benefit material is different fromthe second concentration of hydrophobic benefit material. Thus, thepersonal-care article of the present invention comprises a personal-careproduct that changes in moisturization level as it is dispensed from thepackage which overcomes the problem of a regime that involves too manysteps or too many containers.

The term “personal-care product,” as used herein, may include, but isnot limited to: antiperspirants, deodorants, lotions (e.g. hand lotionand body lotion), skin-care compositions (e.g., face and neck lotions,serums, sprays), sunless tanners, cosmetic compositions (e.g.,foundation, concealer, blush, lipstick, lip gloss), depilatories,shampoos, conditioning shampoos, hair conditioners, body washes,moisturizing body washes, shower gels, skin cleansers, cleansing milks,hair and body washes, in-shower body moisturizers, pet shampoos, shavingpreparations, after-shaves, razor moisturizing/lubricating strips, razorshave-gel bars, bar soaps, cleansing compositions, feminine-careproducts, oral-care products, and baby-care products.

The term “personal-care composition,” as used herein, refers tocompositions intended for topical application to the skin or hair.Compositions of the present invention may be leave-on formulations—inwhich the product is applied topically to the skin or hair and left onfor a period of time, or rinse-off formulations—in which the product isapplied topically to the skin or hair and then is subsequently rinsedwithin minutes from the skin or hair with water, or otherwise wiped offusing a substrate with deposition of a portion of the composition. Thepersonal-care composition of the present invention is typicallyextrudable or dispensible from a package. In other embodiments, thepersonal-care article may not comprise a package at all—for instance, inthe case of bar soap. The personal-care compositions of the presentinvention can be in the form of solid, semi-solid, liquid, semi-liquid,cream, lotion or gel compositions intended for topical application toskin. The term “package” includes any suitable container forpersonal-care compositions including but not limited to a canister,bottle, tottle, tube, jar, non-aerosol pump and mixtures thereof. Asused herein “tottle” refers to a bottle which rests on the neck or mouthwhich its contents are filled in and dispensed from, but it is also theend upon which the bottle is intended to rest or sit upon for storage bythe consumer and/or for display on the store shelf, as described in thecommonly owned U.S. patent application Ser. No. 11/067443 filed on Feb.25, 2005 to McCall, et al, entitled “Multi-phase Personal-CareCompositions, Process for Making and Providing, and Article ofCommerce.”

The term “dispensing orifice,” as used herein, refers to any opening ina package through which product may be dispensed and/or applied. Forexample, an antiperspirant package may comprise a dispensing orifice inthe form of an application surface. The application surface may be anantiperspirant product itself or the application surface may be aperforated or mesh-like dome through which antiperspirant productpasses.

The term “stable” as used herein, unless otherwise specified, refers toa personal-care product that comprise at least two compositions thatmaintain at least two “separate” zones with at least two separatebenefit concentrations zones contained within a package comprising atleast one chamber at ambient conditions for a period of at least about180 days. By “separate” is meant that there is substantially no mixingof compositions contained in said zones, detected by the benefitanalysis method, described hereinafter, prior to dispensing of thecomposition.

The term “structured,” as used herein means having a rheology thatconfers stability on the personal-care composition. The degree ofstructure is determined by characteristics determined by one or more ofthe following methods the Yield Stress Method, or the Zero ShearViscosity Method or by the Ultracentrifugation Method, all in the TestMethods below. Accordingly, a surfactant phase of the composition of thepresent invention is considered “structured,” if the surfactant phasehas one or more of the following properties described below according tothe Yield Stress Method, or the Zero Shear Viscosity Method or by theUltracentrifugation Method. A surfactant phase is considered to bestructured, if the phase has one or more of the followingcharacteristics:

-   A. a Yield Stress of greater than about 0.1 Pascal (Pa), more    preferably greater than about 0.5 Pa, even more preferably greater    than about 1.0 Pa, still more preferably greater than about 2.0 Pa,    still even more preferably greater than about 3 Pa, and even still    even more preferably greater than about 5 Pa as measured by the    Yield Stress and Zero Shear Viscosity Method described hereafter:-   B. a Zero Shear Viscosity of at least about 500 Pascal-seconds    (Pa-s), preferably at least about 1,000 Pa-s, more preferably at    least about 1,500 Pa-s, even more preferably at least about 2,000    Pa-s; or-   C. a Structured Domain Volume Ratio as measured by the    Ultracentrifugation Method described hereafter, of greater than    about 40%, preferably at least about 45%, more preferably at least    about 50%, more preferably at least about 55%, more preferably at    least about 60%, more preferably at least about 65%, more preferably    at least about 70%, more preferably at least about 75%, more    preferably at least about 80%, even more preferably at least about    85%.

The term “surfactant component” as used herein means the total of allanionic, nonionic, amphoteric, zwitterionic and cationic surfactants ina phase. When calculations are based on the surfactant component, waterand electrolyte are excluded from the calculations involving thesurfactant component, since surfactants as manufactured typically arediluted and neutralized.

As used herein the term “zone” is a domain or region within a packagewhich corresponds to a composition of the personal-care product. A zonewithin a package is in direct physical contact with another zone withina package, such that the compositions corresponding to the zone are indirect physical contact with one another. An interface between the zonescan be distinct or gradual or separated by another zone. The amountcontained within a zone can be defined by a percentage of the packagevolume and a zone comprises at least 10% of the package volume of agiven package, excluding the volume of the package corresponding to theclosure, as shown in FIGS. 1A and 1B of the present invention.

All percentages, parts and ratios are based upon the total weight of thecompositions of the present invention, unless otherwise specified. Allsuch weights as they pertain to listed ingredients are based on theactive level and, therefore, do not include solvents or by-products thatmay be included in commercially available materials, unless otherwisespecified. The term “weight percent” may be denoted as “wt. %” herein.Except where specific examples of actual measured values are presented,numerical values referred to herein should be considered to be qualifiedby the word “about.”

All molecular weights as used herein are weight average molecularweights expressed as grams/mole, unless otherwise specified.

The present invention relates to a personal-care article that provides apackage comprising a personal-care product. The personal-care productcomprises at least two personal-care compositions, each compositionhaving a noticeably distinct hydrophobic benefit material concentration.These distinct concentrations can be dispensed sequentially from thepackage. For example, a package could dispense a high level ofhydrophobic benefit material, followed by a composition with a mediumlevel of hydrophobic benefit material, followed by a composition with alower level of hydrophobic benefit material concentration. Thus, thepersonal-care product changes in moisturization level as it is dispensedfrom the package which overcomes the problem of a regime that involvestoo many steps or too many containers.

The present invention relates to a personal-care article for providingat least two personal-care compositions. The personal-care articlecomprises a package and a personal-care product. The package comprisesat least one chamber, a dispensing orifice, a first zone proximate tothe dispensing orifice and a second zone distal to the dispensingorifice. The first zone and second zone are both located in at least onechamber. The personal-care product comprises a first personal-carecomposition substantially disposed within the first zone and the secondpersonal-care composition substantially disposed within the second zone.In one aspect, the first zone is in physical contact with the secondzone within the package. In one aspect, the first personal-carecomposition is in physical contact with the second personal-carecomposition within the package.

The personal-care article for dispensing and or applying at least twopersonal-care compositions comprises a package that comprises at leasttwo zones with at least two personal-care compositions substantiallydisposed within the respective zones. The number of zones with a packageand thus, the number of personal-care compositions disposed within therespective zone can vary in number. For example, the package may havethree zones and three personal-care composition within the respectivezones; four zones and four compositions, five zones and fivecompositions, and so on. In one aspect, the personal-care articlecomprises a third zone medial to the dispensing orifice. In one aspect,the personal-care article comprising a third personal-care compositionsubstantially disposed within the third zone; the third personal-carecomposition comprising a third concentration of a hydrophobic benefitmaterial wherein the third concentration is different from the firstconcentration and the second concentration. In another aspect, the firstzone, the second zone and the third zone comprise an equal percentage,by volume, of the package.

In another aspect, each personal-care composition may comprise a dye,colorant or the like, such that each personal-care composition is adistinct color or hue. For example, the first personal-care compositioncan be a yellow color, the second personal-care composition can be anorange color and the third personal-care composition can be a purplecolor.

The amount of hydrophobic benefit materials in compositions are usuallyformulated, by weight of the composition, at less than about 55%, lessthan about 45%, less than about 30%, less than about 20%, less thanabout 10%, less than about 5%, less than about 4%, less than about 3%,less than about 2%, less than about 1%. Each personal-care compositionmay comprise from about 1.0% to about 60%, from about 5% to about 60%,from about 10% to about 50%, from about 20% to about 45%, by weight ofthe personal-care composition, of a hydrophobic benefit material. In oneaspect of the personal-care article of the present invention, the firstpersonal-care composition or the second composition of the presentinvention may comprise a concentration of 0% hydrophobic benefitmaterial.

The compositions of the present invention can be multi-phase andcomprise one of more phases or one or more of the components describedin the phases below:

The personal-care composition of the present invention can comprise acleansing phase comprising components of the cleansing phase. Thepersonal-care composition typically comprises from about 1% to about100%, by weight of the composition; from about 5% to about 85%; byweight of the composition, from about 10% to 80%, by weight of thecomposition; from about 20 to 70%, by weight of the composition; fromabout 25% to 60%, by weight of the composition, from about 30% to about50%, by weight of the composition, of a cleansing phase.

The cleansing phase can comprise a structured domain that is comprisedof a mixture of surfactants. The presence of structured domain enablesthe incorporation of high levels of hydrophobic benefit materials in aseparate phase which is not emulsified within composition. In oneaspect, the structured domain in the composition can be characterizedas, or is, an opaque structured domain. In one aspect, the opaquestructured domain can be characterized as, or is, a lamellar phase. Thelamellar phase produces a lamellar gel network. The lamellar phase canprovide resistance to shear, adequate yield to suspend particles anddroplets and at the same time provides long term stability, since it isthermodynamically stable. The lamellar phase tends to have a higherviscosity thus minimizing the need for viscosity modifiers.

In one aspect, cleansing phase can comprise a domain that is comprisedof a mixture of surfactants and can be a micellar phase. A micellarphase is optically isotropic. Micelles are approximately spherical inshape. Other shapes such as ellipsoids, cylinders, and bilayers are alsopossible. In one aspect, the micellar phase can be structured to enhanceviscosity and to suspend particles. This can be accomplished usingviscosity modifiers such as those defined below as water structurants.

The cleansing phase comprises a surfactant component which can becomprised of a mixture of surfactants including lathering surfactants ora mixture of lathering surfactants. The cleansing phase comprisessurfactants suitable for application to the mammalian skin or hair whichare compatible with water and the other ingredients of the compositionof the present invention. These surfactants include anionic, nonionic,cationic, zwitterionic, amphoteric, soap, or combinations thereof.Preferably, anionic surfactant comprises at least 40% of the surfactantcomponent. The personal-care composition can comprise the surfactantcomponent at concentrations ranging from about 2% to about 40%, fromabout 4% to about 25%, about 1% to about 21%, about 3 to 15%, by weightof the composition, of the surfactant component.

Test Methods Benefit Analysis Method:

This method determines the weight ratio of cleansing (surfactant) phaseto lipid phase in dual phase composition. A sample of dual-phasecomposition is mixed and tested using a moisture analyzer for %moisture. The result is calculated by dividing the total % moisture inthe composition by the % moisture in the surfactant phase thenmultiplying that result by 100. The % benefit agent (lipid) iscalculated by subtracting the % surfactant phase from 100. It isapplicable only to dual phase compositions in which one phase (lipd)contributes no volatiles at the temperature conditions used in theinstrument program.

Apparatus: Infared or Halogen Moisture Balance (e.g. Programed accordingto the operating manual, Mettler-Toledo HR73 Moisture Analyzer) usingthe following test parameters: Heating mode: Ramp to 140° C. in 5minutes Switchoff mode: 3 aluminum drying pans (4 inch × 5/16 inchAluminum drying pans must be dried and deep) stored in a desiccatorprior to use. Dry the pans in a conventional oven for 1 hour at 130° C.Allow pans to cool to room temperature before using. Always handle panswith a clean pair of forceps 1 ml Disposable Syringes Analytical Balancecapable of weighing to 3 decimal places

T-Bar Viscosity Method:

The viscosity of a composition contained within a zone can be assessedby the T-Bar Viscosity Method. In the case of testing from a productpackage, two zones can be selected from the package that contains atleast two compositions that contain separate hydrophobic benefitmaterial concentrations. In order to separate the zones, the product canbe frozen at a temperature of at least −20° C. for a period of at least24 hours. The zones are then cut using a cutting implement such as abandsaw. The cut portions are collected separately and allowedequilibrate to ambient conditions.

The apparatus for T-Bar measurement includes a Brookfield DV-II+ProViscometer with Helipath Accessory; chuck, weight and closer assemblyfor T-bar attachment; a T-bar Spindle D, a personal-computer withRheocalc software from Brookfield, and a cable connecting the BrookfieldViscometer to the computer. First, weigh 80 grams of the first or secondcomposition in a 4-oz glass jar. Measure the T-bar viscosity bycarefully dropping the T-Bar Spindle to the interior bottom of the jarand set the Helipath stand to travel in an upward direction. Open theRheocalc software and set the following data acquisition parameters: setSpeed to 5 rpm, set Time Wait for Torque to 00:01 (1 second), set LoopStart Count at 100. Start data acquisition and turn on the Helipathstand to travel upward at a speed of 22 mm/min The T-Bar viscosity “T,”is the average T-Bar viscosity reading between the 6^(th) reading andthe 95^(th) reading (the first five and the last five readings are notused for the average T-Bar viscosity calculation). If the viscosity isbelow the lower limit of the D spindle (30,000 cps), a larger spindlecan be used for the T-Bar Viscosity measurement.

Ultracentrifugation Method:

The Ultracentrifugation Method is used to determine the percent of astructured domain or an opaque structured domain that is present in amulti-phase personal-care composition that comprises a structuredsurfactant phase comprising a surfactant component. The method involvesthe separation of the composition by ultracentrifugation into separatebut distinguishable layers. The multi-phase personal-care composition ofthe present invention can have multiple distinguishable layers, forexample a non-structured surfactant layer, a structured surfactantlayer, and a benefit layer.

First, dispense about 4 grams of multi-phase personal-care compositioninto Beckman Centrifuge Tube (1×60 mm) Next, place the centrifuge tubesin an Ultracentrifuge (Beckman Model L8-M or equivalent) andultracentrifuge using the following conditions: 50,000 rpm, 18 hours,and 25° C.

After ultracentrifuging for 18 hours, determine the relative phasevolume by measuring the height of each layer visually using anElectronic Digital Caliper (within 0.01 mm) First, the total height ismeasured as H_(a) which includes all materials in the ultracentrifugetube. Second, the height of the benefit layer is measured as H_(b).Third, the structured surfactant layer is measured as H_(c). The benefitlayer is determined by its low moisture content (less than 10% water asmeasured by Karl Fischer Titration). It generally presents at the top ofthe centrifuge tube. The total surfactant layer height (H_(s)) can becalculated by this equation:

H_(s) =H _(a) −H _(b)

The structured surfactant layer components may comprise several layersor a single layer. Upon ultracentrifugation, there is generally anisotropic layer at the bottom or next to the bottom of theultracentrifuge tube. This clear isotropic layer typically representsthe non-structured micellar surfactant layer. The layers above theisotropic phase generally comprise higher surfactant concentration withhigher ordered structures (such as liquid crystals). These structuredlayers are sometimes opaque to naked eyes, or translucent, or clear.There is generally a distinct phase boundary between the structuredlayer and the non-structured isotropic layer. The physical nature of thestructured surfactant layers can be determined through microscopy underpolarized light. The structured surfactant layers typically exhibitdistinctive texture under polarized light. Another method forcharacterizing the structured surfactant layer is to use X-raydiffraction technique. Structured surfactant layer display multiplelines that are often associated primarily with the long spacings of theliquid crystal structure. There may be several structured layerspresent, so that H_(c) is the sum of the individual structured layers.If a coacervate phase or any type of polymer-surfactant phase ispresent, it is considered a structured phase.

Finally, the structured domain volume ratio is calculated as follows:

Structured Domain Volume Ratio=H _(c) /H _(s)*100%

If there is no benefit phase present, use the total height as thesurfactant layer height, H_(s)=H_(a).

Yield Stress and Zero Shear Viscosity Method:

The Yield Stress and Zero Shear Viscosity of a composition containedwithin a zone, can be measured either prior to combining the phases in acomposition, or after combining the phases in a composition byseparating the phases by suitable physical separation means, such ascentrifugation, pipetting, cutting away mechanically, rinsing,filtering, or other separation means. In the case of testing from aproduct package, two zones can be selected from the package thatcontains at least two compositions that contain separate hydrophobicbenefit material concentrations. In order to separate the zones, theproduct can be frozen at a temperature of at least −20° C. for a periodof at least 24 hours. The zones are then cut using a cutting implementsuch as a bandsaw. The cut portions are collected separately and allowedequilibrate to ambient conditions.

A controlled stress rheometer such as a TA Instruments AR2000 Rheometeris used to determine the Yield Stress and Zero Shear Viscosity. Thedetermination is performed at 25° C. with the 4 cm diameter parallelplate measuring system and a 1 mm gap. The geometry has a shear stressfactor of 79580 m⁻³ to convert torque obtained to stress. Serratedplates can be used to obtain consistent results when slip occurs.

First a sample of the composition is obtained and placed in position onthe rheometer base plate, the measurement geometry (upper plate) movinginto position 1 mm above the base plate. Excess phase at the geometryedge is removed by scraping after locking the geometry. If the phasecomprises particles discernible to the eye or by feel (beads, e.g.)which are larger than about 150 microns in number average diameter, thegap setting between the base plate and upper plate is increased to thesmaller of 4 mm or 8-fold the diameter of the 95^(th) volume percentileparticle diameter. If a phase has any particle larger than 5 mm in anydimension, the particles are removed prior to the measurement.

The determination is performed via the programmed application of acontinuous shear stress ramp from 0.1 Pa to 1,000 Pa over a timeinterval of 4 minutes using a logarithmic progression, i.e., measurementpoints evenly spaced on a logarithmic scale. Thirty (30) measurementpoints per decade of stress increase are obtained. Stress, strain andviscosity are recorded. If the measurement result is incomplete, forexample if material flows from the gap, results obtained are evaluatedand incomplete data points excluded. The Yield Stress is determined asfollows. Stress (Pa) and strain (unitless) data are transformed bytaking their logarithms (base 10). Log(stress) is graphed vs.log(strain) for only the data obtained between a stress of 0.2 Pa and2.0 Pa, about 30 points. If the viscosity at a stress of 1 Pa is lessthan 500 Pa-sec but greater than 75 Pa-sec, then log(stress) is graphedvs. log(strain) for only the data between 0.2 Pa and 1.0 Pa, and thefollowing mathematical procedure is followed. If the viscosity at astress of 1 Pa is less than 75 Pa-sec, the zero shear viscosity is themedian of the 4 highest viscosity values (i.e., individual points)obtained in the test, the yield stress is zero, and the followingmathematical procedure is not used. The mathematical procedure is asfollows. A straight line least squares regression is performed on theresults using the logarithmically transformed data in the indicatedstress region, an equation being obtained of the form:

Log(strain)=m*Log(stress)+b   (1)

Using the regression obtained, for each stress value (i.e., individualpoint) in the determination between 0.1 and 1,000 Pa, a predicted valueof log(strain) is obtained using the coefficients m and b obtained, andthe actual stress, using Equation (1). From the predicted log(strain), apredicted strain at each stress is obtained by taking the antilog (i.e.,10^(x) for each x). The predicted strain is compared to the actualstrain at each measurement point to obtain a % variation at each point,using Equation (2).

% variation=100*(measured strain−predicted strain)/measured strain

The Yield Stress is the first stress (Pa) at which %variation exceeds10% and subsequent (higher) stresses result in even greater variationthan 10% due to the onset of flow or deformation of the structure. TheZero Shear Viscosity is obtained by taking a first median value ofviscosity in Pascal-seconds (Pa-sec) for viscosity data obtained betweenand including 0.1 Pa and the Yield Stress. After taking the first medianviscosity, all viscosity values greater than 5-fold the first medianvalue and less than 0.2× the median value are excluded, and a secondmedian viscosity value is obtained of the same viscosity data, excludingthe indicated data points. The second median viscosity so obtained isthe Zero Shear Viscosity.

The compositions are made as follows:

A water phase is prepared by admixing all water soluble ingredients,except sodium hydroxide and Prodew 400, in water and heating to about80° C. A second premix is prepared by admixing of the oil solubleingredients except the silicone oil (DC1503) and heating also to around80° C. The oil phase is added to the water phase and sheared to form anemulsion.

The emulsion is cooled to 60° C. and the polymeric thickener (Sepigel305) is then added. Sodium hydroxide solution is then added toneutralize to pH 6-7.5, except for examples where sunscreens areincluded. At 45-50° C. the benzyl alcohol, Prodew, DC1503, and particles(mica pearls) are added and the resulting product is sheared to ensureparticle dispersion, de-agglomeration and homogeneity. The compositioncan then be cooled to 40° C. and perfume can be added. The compositioncan then be prepared for packaging.

A visually distinct multiphase composition of the present invention canbe prepared by melting the benefit phase and combining at a specifiedratio with a surfactant phase of the present invention in a transparentpackage while the package is rotated. A multiphase composition of thepresent invention can also be prepared by optionally melting the benefitphase and combining with a surfactant phase of the present invention inan agitated tank or using agitation from a static mixer to create adispersion of one phase in the other, then filling the composition intoa package.

Filling the Empty Product Container to Form a Container of MultiphaseComposition

The multiphase personal-care composition can be prepared by any suitablemeans. For example, filling the empty product container with themultiphase personal-care composition can comprise transferringpredetermined amounts of the different phases through at least onedispensing means into an empty product container. Additionally, themultiphase personal-care compositions can be prepared by the method andapparatus as disclosed in U.S. Pat. No. 6,213,166 issued to Thibiant, etal. on Apr. 10, 2001. The method and apparatus allows two or morecompositions to be filled with a spiral configuration into a singlecontainer. The method requires that at least two nozzles be employed tofill the container. The container is placed on a moving stage and spunas the composition is introduced into the container.

Alternatively, it is effective to combine at least two phases by firstplacing the separate compositions in separate storage tanks having apump and a hose attached. The phases are then pumped in predeterminedamounts into a single combining section. Next, the phases are moved fromthe combining sections into a blending section and the phases are mixedin the blending section. The next step involves pumping the product thatwas mixed in the blending section via a hose into a single nozzle, thenplacing the nozzle into a container and filing the container with theresulting product such that the single resulting product exhibits avisually distinct non-random pattern of the phases.

The shape and size of the particular product container used will dictatethe rate of filling, rotation of the bottle, frequency of rotation ofthe bottle, and movement of the bottle during filling, as these factorscan have a direct impact on the shape, size, and overall appearance ofthe pattern in the multiphase composition. The starting position of thebottle (proximity to the multiphase dispenser, as well as relativeposition when initially being filled), also affect the appearance of thepattern in the multiphase composition.
